Sequencing order between functions and signals

Hello,

I read in many places that the sequencing order of the functions of a HAL file is done by the order of addf creation for each function in a given thread. This is clear.

But, when you have signals connected in between pins of these functions, when those signals are evaluated ? What is the rule ?
I read the HAL User Manual. I could not find any word about this. May be it is intuitive but not for me...

Thanks

When a function is run by it's thread, that is when it reads the hal pins going to it, and then writes to the hal pins going out of it. You can think of the signals as memory storage addresses.

Thanks Todd
